Split the given string into two parts. If there is only one resulting part, that part will be the second return value and the first return value will be empty.

func SplitPairTrailing 

func SplitPairTrailing(in string, delimiter string) (string, string)

Split the given string into two parts. If there is only one resulting part, that part will be the second return value and the first return value will be empty.

func SplitTriple

Types

type ConvertType 

type ConvertType = utils.ConvertType

func ParseType 

func ParseType(name string) ConvertType

type InterceptFunc 

type InterceptFunc func(seq []byte)

type OnlySqueezeFunc added in v1.6.19 

type OnlySqueezeFunc func(r rune) bool

type ScanInterceptor 

type ScanInterceptor struct {
	Disabled bool
	// contains filtered or unexported fields
}

A ScanInterceptor is used as a SplitFunc on a bufio.Scanner. It will look at the stream of bytes being scanned for specific substrings. The registered handler function associated with a substring will be called whenever it is seen in the stream. The passthrough SplitFunc is called as normal. This allows for a stream to be split and processed while also being inspected for specific content, allowing the user to react to that content as it comes by.

func NewScanInterceptor 

func NewScanInterceptor(passthrough bufio.SplitFunc, intercepts ...map[string]InterceptFunc) *ScanInterceptor

func (*ScanInterceptor) BytesScanned 

func (self *ScanInterceptor) BytesScanned() int64

Return the total number of bytes this scanner has scanned.

func (*ScanInterceptor) Intercept 

func (self *ScanInterceptor) Intercept(sequence string, handler InterceptFunc)

Add an intercept sequence and handler. If the sequence is already registered, its handler function will be replaced with this one.

func (*ScanInterceptor) InterceptCounts 

func (self *ScanInterceptor) InterceptCounts() map[string]int64

Returns a map of intercept sequences and the number of times each one was fired.

func (*ScanInterceptor) Scan 

func (self *ScanInterceptor) Scan(data []byte, atEOF bool) (advance int, token []byte, err error)

Implements the bufio.SplitFunc function signature for use in a bufio.Scanner.

type SiPrefix 

type SiPrefix int

func GetSiPrefix 

func GetSiPrefix(input string) (SiPrefix, error)

func (SiPrefix) String 

func (self SiPrefix) String() string
